Description
Technical field
The utility model relates to coal-mine gas pump drainage technical field, particularly relates to a kind of proving installation measuring intumescent material swells pressure.
Background technology
Expanding material is a kind of non-harmful crushing material, be widely used in the field such as stone mining, rock failure, extending to mining and improvement field, wherein turgor pressure is used to weigh the topmost performance index of expanding material, is directly connected to exploitation effect.In addition, the hydration reaction temperature influence of expanding material is very large, too fast in high temperature more than 40 DEG C aquations, easy spray orifice; Below 0 DEG C, aquation is too slow, crushing effect extreme difference.Test at present to intumescent material swells pressure, relatively more conventional method has outer tube method, interior tube method and pressure transducer, and these three kinds of method of testings are all the strain values utilizing foil gauge to measure reaction, thus draws turgor pressure.The shortcoming of these measuring methods is that test technology is complicated, test result precision is not high, release amount of heat, large to electronic component harm, can not reuse, thus raise the cost, the most important thing is that expanding material acts on when being broken thing and form damage zone, inside, damage zone produces stress relief, reduces expansion resistance, so these three kinds of methods can not truly measure turgor pressure and temperature.
Utility model content
For prior art Problems existing, the utility model provides that a kind of test technology is simple, measuring accuracy is high and the proving installation of reusable measurement intumescent material swells pressure, and can measure the turgor pressure of non-damaging stage and injury stage respectively.
